What is a main board?

The main board is basically the “brains” of your TV and controls everything, from the audio to video streams. All of the user data and settings are also stored on the main board.

Which symptoms does a main board fix in a TV?

• If your TV doesn’t turn on, it could be the main board. If your TV turns on but has no video and/or no audio, it could also be the main board.

• If one HDMI input works but others don’t work, it could be the main board.

*These are helpful tips to get you started and don’t represent accurate diagnoses for every TV model and failure. If you’re unsure of your diagnosis, we recommend checking out our YouTube channel or reaching out to a local TV technician for assistance.

How easy is it to replace a main board?

It's easy! Once you match the part number on your main board with the part number listed on this page to confirm compatibility, you’ll just need a screwdriver and the ability to remove the back of your TV and replace the board.

We recommend matching the part number on your original part with the part number listed on this page to ensure compatibility.

While matching your model number is a great start, many models use variations of each part and they're not always interchangeable.

We include brief instructions in red text on some listings (also displayed below without the red font). Please look for these instructions to confirm any important info that you'll need to identify on your original part. Additionally, we highlight the part number in our photos.

Please don't hesitate to contact us with any questions. We're here to help!
